For exceptional value and durability, snuggle up in a Duck Down duvet containing light down clusters and small, fluffy feathers. The duvet offers a heavier feel than a goose down duvet with its higher feather content but still provides exceptional warmth and comfort. The natural filling enables the body to breathe as it allows excess humidity created by the body during sleep to escape resulting in a refreshing night’s sleep. The All Seasons duvet is made up of two duvets that can be used separately or together; a 4.5 tog for summer, and a 9.0 tog for autumn.
